minirst: dynamically compile admonitions regexp Currently, parsing admonitions uses a static regular expression created from a pre-defined list of admonitions. A future patch will introduce a feature that needs to parse custom admonitions. Prepare for this by compiling the admonitions regular expression during each function invocation. Strictly speaking, there is a slight performance loss here. But we only run this code as part of displaying help text. I don't think the loss will be noticeable and I don't think we care if it were.

minirst: detect bullet lists using asterisks Previously, the "bullet" regular expression excluded the asterisk ('*') as a character denoting a bulleted list. Why I'm not sure because the asterisk seems to be the canonical bullet character in reST these days. This patch makes asterisk-prefixed lines parse as bulleted lists.

color: update the help table We also need to reference the new topic in the great old help table.

ui: remove superfluous indent in _write()

smartset: reorder initialization of baseset in more intuitive way What we want to do is to assign either _set or _list per the given data type.

config: update the Windows example config file We move from the color extensions to the 'ui.color' config.

help: use 'churn' instead of 'color' as an example extension The 'color' extensions is now deprecated.

config: suggest the 'ui.color' instead of the 'color' extension The extensions is deprecated now so we should offer the core way to handle color instead.

color: update main documentation Now that the feature no longer lives in the extension, we document it in the help of the core config. This include the new 'ui.color' option introduced in the previous changesets. As a result the color extensions can now be deprecated. This is a documentation patch only; color is still disabled by default.

pager: drop the 'color' dependant code The 'color' implementation is in core and no longer wrap '_runcommand'. We drop the extra complexity.
